HOPPER-CAR.

- Application filed January 22, 1916. Serial 1%. 78,571

To all whom it may concern:

Be it known that I, ARGYLE CAMPBELL,

a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois have invented a certain new and useful Improvement in Hopper-Cars, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forming a part of this specification.

This invention relates to improvements in hopper cars.

An object of the invention is to provide a hopper car, particularly of the so-called W type having increased load carrying capacity as compared with present types now in service.

Another object of'the invention is to pro. vide a hopper car having increased capacity 0 as compared with present commercial types wherein part of the load is carried loy an improved type of hopper door.

A still further object of the invention is to provide a hopper car of the W type which may be made longer than those now in use to thereby increase its capacity and at the same time maintain the height and slope of the central, transverse cross ridge of the car.

The invention furthermore consists in improvements in the parts and devices and in the novel combinations of the parts and devices hereinafter described and made the subject matter of claim.

in the drawing forming a part of this 5 specification, Figure l, is a part side elevation and part longitudinal section of a hopper car showing my improvement in connection therewith. Fig. 2 is an enlarged detail, vertical sectional-view near the lone the proved arrangement, the dotted lines indicating one of the hopper doors in open position and other dotted lines heing employed to more clearly illustrate the method of obtaining increased capacity. Fig. 3 is an enlarged, vertical transverse sectional view taken substantially on the line 3-3 of Fig. 2. And Fig. 4 is another detail, sectional view similar to Fig. 2 illustrating a difierent type of hopper door which may be employed in carrying out my invention.

In said drawing, -40 denote the side walls of a W type of car, 1i11 the downwardly and inwardly inclined hopper hot- 5 tom sheets, 1212 the inner longitudinal hinge pin 25.

tom hopper sheets 11 and the lower edges of the inclined ridge sheets 15.

The improved hopper doors are designated generally by the reference A and, as shown, each hopper door A is of substantially scoop or pan shape and is provided with a vertically extending back wall 16, a lower horizontal bottom wall 17 arranged substantially at right angles to the hack wall 16 when the door is in closed position, and side walls 1818. Each door A is provided on its sides with upwardly extending brackets 19-19 flanged at their edges as indicated at 20 for strength, each of said brackets 19 having a hinge'casting 21 at its upper end, the outer hinge casting 21 being pivotally mounted on a hinge pin 22 supported in suitable castings 23 and 24, secured respectively. to the inner side of the longitudinal hopper sheet 14 and lower portion of the side wall 10. Each of the inner hinge castings 21 is pivotally mounted on a hinge pinl25 which extends through the center sill and the ofiset portion 13 of the -inner longitudinal hopper sheets 1'2, the latter having suitable hearing brackets 262'd fastened thereto to form a proper support for the The upper transversely extending edge of each hopper door 18 is adapted to fit over an angle iron 2'? secured to the under side of the lower edge of the ridge sheet 15 and at its lower transverse edge,.each hopper door A is ofiset from the main bottom portion 17 as indicated at 28, and is further provided with an edge flange 29 adapted to fit over an angle 30 secured to the under side of the lower edge of the-hottom hopper sheet 11. It will also he apparent that the sides 1818 of each hopper door A lit over the outwardly ofiset portions 13 of the inner longitudina sheets 12 and the outer longitudinal sheets 14 whereloythe.

door openings are properly sealed when the hopper doors are in closed position.

As appears from an inspection of Figs. 1 and 2, the doors swing about axes located a considerable distance above of the door openings so that as the doors are swung open, they clear the rail 31.. Any suitable door operating mechanism may be employed, that shown in the drawing comprising a transversely extending channel 353 connected to the undersides of a pair of doors, a bracket 33 secured to said channel between the hoppers, an eye bolt 342 mounted on said bracket and channel, an elongated. hook shaped link 35 pivoted to the eye bolt 34, a short link 36 pivoted to the link 35 and another link 37, the latter in turn being pivoted to an arm 38 formed integrally with a drum tired to a trans versely extending operating shaft 39. The latterv extends to the sides of the car and is provided with any suitable form of ratchet d0, pawl 41 cooperable therewith and locking cam Q2. The door mechanism is of a well known type and is so arranged that when the doors are in closed position, tendency of the shaft to rotate is eliminated on account of the hook shaped linlr 35 engaging the drum to one side oi a line drawn between the axis of the operating shalt and the pivotal connection between the eye bolt 34: ahd link 35. As will be understood, the doors are operated in pairs, there being two sets of door operating mechanisms.

By reiferring to Fig. 2, it will be seen that the slope and height of the ridge sheets 15 are maintained even though the length of the car is increased. H the arrangement which l have shown were not employed and the car were lengthened as compared with those now in service, the ridge sheets would necessarily occupy the position indicated atdotted lines 43 since the usual type of door and hinging arrangement would have necessitated hinging the doors at a point as indicated at 44, in order that the doors could swing and properly clear the rail. Hence, it will be seen that with my improved arrangement ll obtain the additional capacity represented by the volume between the ridge sheets 15 and the imaginary location oi the ridge sheets indicated at'43 and the additional triangular shaped volume located by the dotted line 45. Furthermore, by employing hopper doors of the character shown and described ll obtain additional capacity equivalent to four times the load carrying capacity of each scoop or pan shaped door. lln this connection, it will be understood, ofi course, that the slope of the ridge sheets is necessarily determined by the material which the car is designed to carry in order to insure a complete discharge oi the load and prevent bridging or arching oil the load.

the top edges side sheets of the respective hopper.

In the form shown in Fig. 4c, the arrangement of hopper sheets, ridge sheets, door operating mechanism, door hinging devices, and location of the door hinge points are the same as those in the car illustrated in lFigs. 1, 2 and 3. lhe hopper door A, however, approaches more nearly the hopper doors now in use and illustrates that such a type of hopper door may be employed and still obtain increased capacity for the car by pivoting it in the manner described, as it will be obvious that with this arrangement l also obtain the increased capacity heretofore described in connection with the ridge sheets.

l have herein shown and described what l.

now consider the preferred means of carrying out my invention but the same is merely illustrative and l contemplate all changes and modifications that come within the scope the claims appended hereto.
